CONTINUOUS BRICK-KILN.

SPECIFICATION forming part of Letters Patent No. 510,135, dated December5, 1893. Application filed February 13, 1893. Serial No. 462,120. (Nomodel.)

To all whom it may concern.-

Be it known that I, JAMES HENNEY, a citizen of the United States,residing at Cloverport, in the county of Breckinridge, State ofKentucky, have invented certain new and useful Improvements inBrick-Kilns; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the lettersof reference marked on the accompanyingdrawings, which form a part of this specification.

My invention relates to brick or pottery kilns.

The invention consists in the following construction and combination ofdevices, the features of which will be fully set forth and described andthe points of novelty set forth in the claims. .A

Figure l represents a transverse vertiea section of a series of kilns towhich I have applied my improvements. Fig. 2 is a side elevation of oneof the kilns. Fig. 3 is a detail view of a pipe connection.

In the drawings-A, B, C represent a series of kilns.

E are the usual chimneys.

F are the flash walls.

G is an arch.

His a perforated door, and I, the llues leading from the floors to thedraft chimneys E. The kilns are of the down-draft variety.

K is a horizontal pipe connecting the whole series of kilns, it formingthe llue passage controlled by certain valves, so that the heat from anyone or more kilns may be diverted into any one or more rvkilns of theseries.

In Fig. 2, L represents a horizontal header along the top of the arch,and provided with a series of short `downwardly projecting lue passages,connected with a header, 'whereby the heat may pass freely to or fromthe kiln.

We will suppose, for an illustration, that the kiln C is full of bricks,the burning of which has just about been completed, and

that the kiln B is stacked with green bricks. Now for the purpose ofeconomically utilizing the residue heat in the kiln C, which wouldotherwise be wasted, the valve N, of the flueK is opened, and the valveO closed. The heat from the kiln C will thus pass upwardly, as shown inthe arrows, through the series of short flues M, into the header Landalong the flue K down into kiln B, for the purpose of drying out andutilizing to the full extent possible the spent heat of the kiln C. Inlike manner should we wish to divert the heat into both kilns A and B,the valveO would be opened for this purpose. Similarly one ora series ofkilns which may be joined by my system may be connected vwith theresidue heat from any one or more of the kilns which may be red.

I provide' each of the short flues M with a damper, or cut-off P, bymeans of which any particular kiln or flue may be cut out of the series,shouldthe heat not be wanted for that kiln.

For the purpose of initiating a draft through the manifoldsandflue-pipes L, I may connect said pipes with the chimneys E, here andthere, as shown at W, in order to superinduce the draft through theflue-pipes, until they get hot; after which the connections W may beshut off, and the heat pass down through the kiln or'kilns desired andout the chimneys.

I claim, furthermore- A series of kilns provided with manifolds havingalong their crowns and in connection with the arch, a series offlue-pipes connecting said manifolds, connections between said lines andthe chimneys direct, and a series of valves in the line-pipes.

In testimony whereof I aiiix my signature in presence ot' two witnesses.

JAMES IIENNEY.
